This inventionA relates to'wipers for gauge As is well known to those familiar with the art, vmany manufacturers of automobile engines provide gauge rods whlch extend into the'oil sump of the'ef'n'gine and which, when withdrawn, are supposed to provide an indication of the depth of oil in the sump. In actual yuse, such rods are worthless after the engine has been operated, unless they are wiped before use, for the reason that oil lashed about in the base ofthe engine, t oroughly covers the same and thus fai'ls tov leave an legible indication of thev actual depth of oil in the sump. Accordingly, an important object of vthe present invention is the provision of a device which may be conveniently positioned and which will provide a ready means for cleansing the rod of any collected oil.Y

A further object of the invention'is to produce a device of this character of 'such structure that the collection of dirt therel on, which might be thus transferred to the lng approximately the position which the irse,

rod and from the rod to the oilin the sump, is eectually prevented A still further object of the invention is to rovide a structure such that the wiping pad) will at all times have good contact with the rod and thus insure removal of oil thereclosed position of the casing which a'gauge rodv 23 may he introduced to from. f

These and other objects we attain by .the construction shown 1n the accompanylng drawings, wherein forl the purpose of illustration is shown a preferred embodiment of our invention and wherein n Figure 1 is a diagrammatic view illustratdevice will occupybeneath the hood of" automobile; 4, Figure 2 is a sectional view-onf'thainle' 2 2 0f Fi Ie 3;

Figure 3 1s a side elevation of the wiper Figure 4 is a section on the'4 line 4--4 o ,-Figure 3, a ortion of the ears` of the cas :ing sections ing broken away.

,f igure 5 is a' view similar to that of Figure tiene.

@Referring now more particularly to the drawings, the wiper comprises a pair of felt pads 10 and 11 and means. for supporting and housing these-pads. In the present instance, each ad 10 and 11 isl shown as formed of a plur ity of layers of felt stitched together illustrating a f slightly modified construc- -at vtheir centers and adjacent one end, as indicated at 12, by stitching, which constricts the pads, slightly reduclng the thickness thereof at this point, for a purpose presently to appear. c

' Means for supporting and housing these pads comprises a casing formed in two seotions 18 and 14 separablel from one another and each of'a size to hold the' pad 10 or 11. The casing sections along their side edges are provided with vears 15, the ears of Vthe section 13 being threaded at llfor engage- DY, or snasrnn HEIGHTS,

ment withheaded securing elements 17, the

Shanks of which pass through openings 18y formed in the 'ears 15 of the section 14. Between the heads of the securing elements and the ears 15 of thesection 14, springs 19 are disposed, which constantly'urge the sections 14 in a direction such that the casing closes; l'The section 13 is provided with an attaching lug 20 for engagement with a bracket, generally indicated at 21,'by means of which the device may be attached to either the wall of an engine orto any other stationary portion of the vehicle at a 'convenientA point. c

Adjacent faces of the casingl sections at the upper end wall of the casing are notched at 22, so that anV openin the casing. This opening ali s 4with the socket 2,4 formed by the stitey ed portions of the pads, so that the rod, when introduced to the casing, 'will enter this socket 1s provided in the sectionsthrough and thus be properly lengaged between ad- Y jacent faces of the pads 10 and 1L By'. forcing the rod into the casing, these faces sprin s 19,` will remove any collectedl oil of-'the pads pressed against the` rod by the.V

v therey rom. ln Figure 5, have illustrated a modified structure, wherein-the casing is l..

shortened and the bottom walls of the casing sections.v are provided with-notches'22?v through which the rod may pass. With a" vstructure of this character, the casing may portion of the rod be made shorter than the which-is to be cleaned.

.n wnibeobvious Athat e device or "this l character will provide a .convenient and ecientmeans for cleaning'y the rod and will insure a cleanlng surface which is free frein dirt and dust, so that thereis no danger-of introductionof these substances to the sump of the ene.

It will also be obvious that thefconstruction hereinbeforeset forth is capable di?y a certain range of change and modification without materially departing from the spirit of the rinventlon and We accordingly do not:

y limit `ourselves to such specific structure ex-l 20 means reinforcing ce t as hereinafter claimed.
